Tube types

@yogiboy  thank you. I wasn't aware of the CCa version. I see they're expensive! 

You may find these interesting: https://www.head-fi.org/threads/6922-tube-review-17-top-6922-6n23p-e88cc-cca-7308-e188cc-tubes.761078/ and: https://wallofsound.ca/audioreviews/vacuum-tube-shootout-6dj8-types-part-1/ Keep in mind; there are a plethora of variables(individual tastes/biases/aural acuity, speaker system response/accuracy, electronics, etc) ie: Read Paulo’s post(Wall of Sound site), with which I’d have to agree, 100%(far as audio equipment comments).

@rodman99999  thank you. I'll certainly take a look. I guess tube rolling could potentially be rather expensive in order to find the best combination 

Have you guys found that switching to premium tubes has been a significant improvement?

From my limited tube rolling experiences I found myself agreeing with Joe S.

I have tried many makes & variations of this tube, including the CCa and recommend the Matsushita 7DJ8 as an great performer at a reasonable price.
